In a spacecraft review meeting held with Shea on August 19, 1966 (a week before delivery [of Apollo 1]), the crew expressed concern about the amount of flammable material (mainly nylon netting and Velcro) in the cabin, which both astronauts and technicians found convenient for holding tools and equipment in place.


Considering how fastidious NASA became about fire prevention after the Apollo 1 accident, what steps were taken to mitigate the flammability of Velcro? (For example, the type of material, amount used, etc.)

    $\begingroup$ If they learned from it, that lesson was lost on the space shuttle folks. The cockpit was practically lined in it. I still remember smarting at losing software checkout time in the simulator to 'Velcro mods' time. Check out all the blue Velcro in this pic of Endeavour nasa.gov/images/content/650294main_powerdown-cockpit.jpg $\endgroup$ Mar 19, 2020 at 0:33

    $\begingroup$ @OrganicMarble: Nor has SpaceX learned the flammability lesson. This picture of Crew Dragon sure looks like it has a lot of combustible plastic. $\endgroup$

    $\begingroup$ @DrSheldon, you can't tell how combustible something is just by looking at it. Ordinary plastic and plastic with a heavy mix of flame-retardants look the same. $\endgroup$

    $\begingroup$ @aml are you claiming the Velcro in spacecraft cockpits is made of Nomex? If you can back that up, you should write an answer. $\endgroup$ Mar 19, 2020 at 11:35

    $\begingroup$ I'm fairly sure SOP at SpaceX is to not look at lessons learned by others @DrSheldon $\endgroup$
